There are a number of different types of microscopes and each of them solves unique problems.
A microscope that allows easy observation of 3D objects at low magnification. They can have a very simple design, although complex optical microscopes aim to increase resolution and sample contrast. Once coated in a high conductivity material, the sample slide is scanned in a vacuum.
Since ultraviolet light is used, the resolution of the object increases.
But, there are actually several kinds of microscopes, and each of them functions somewhat differently and serve a variety of purposes. Image 12: A Phase contrast microscope uses a light interference.
It uses the evanescent wave to illuminate the surface close to the specimen.
The microscopic world has proven to contain some of the most beautiful things Nature has for us, after all. While the magnification is only 300x, users can view and even manipulate 3D objects.
A microscope is a laboratory instrument used to see things that are not visible to the human eyes. When it comes to advanced microscopes, research industries often utilize electron and scanning probe microscopes, since these are high resolution and high magnification microscopes that can be used on a variety of specimens. The fluorescent microscope uses ultraviolet light as its light source. These microscopes have a wide range of scientific uses in both physical and medical science.
This microscope does not require slide preparation, so it’s highly suitable for large and opaque specimens. Although this microscope gives lower magnifications than the TEM, the SEM permits three‐dimensional views of microorganisms and other objects. An image is created on a monitor and viewed by the technologist. Another great advantage is that the sample can be stimulated and the reactions or response may be observed, as well as the specimin’s properties. 2. Below each description of the microscope and its use is an image that was captured using that particular microscope.
Therefore, the object is seen poorly and without resolution. It’s highly useful in biology, especially when observing photosynthesis, as well as performing microsurgery and other medical science activities, and even in electronics such as when making circuit boards and timepieces.
Ability to process multiple captured images at high speed makes live imaging of cells possible. Light microscopes have various sub-types which include the following: Image 3: A basic single magnification microscope.
When it comes to studying and observing living cells, an X-ray microscope is often the most suitable option, since it doesn’t require any specimen sample preparation. It’s a powerful and high magnification microscope that is perfect for nanotechnology since it has the power to produce images at the atomic level.
Electron microscopy. The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object. They are similar to biological inverted microscope in the magnification provided, but one primary difference is that the samples are not placed in a petri dish, but rather a smooth side of the sample must be prepared so it can lay flat on the stage.
With a magnification ranging from 50x to 1,500x, this microscope uses sliced samples that are fixed onto slides for observation.

A basic microscope can be used to study somewhat large objects, while specialized and advanced microscopes can go as far as subatomic levels of a single specimen.
